Unlike more dense glass micro balloon-filled syntactic foams, this material greatly reduces tooling wear. The high-density polyurethane foam is easily worked using CAD/CAM routers and CNC machines – or the simplest woodworking tools. The FR-4600’s exceptional machining characteristics also make it an efficient material to create intricately patterned masters for composite and layup tools and for mold and foundry patterns.

Smooth Finish Foam for Tooling & Molds

FR-4600 Microcell Board, designed for tooling use up to 200°F, is well-suited for layup tools with low-temperature curing prepregs, and other low-temperature processes. This superfine tooling material produces remarkably crisp edges with exceptional dimensional stability.
